82fd32d674 * src/cid/cidload.c (cid_hex_to_binary): Improve return value. 
Add argument to return the actual number of bytes that were decoded.
The actual number of bytes decoded can be quite variable depending
on the number of ignored 'whitespace' bytes or early termination
with `>`.
(cid_face_open): Updated to use this calculated value.  This avoids
trusting `parser->binary_length` is always be correct and reading
uninitialized bits if fewer are actually decoded.

66630d882c [sfnt] Streamline POST format 2.0 handing. 
To reduce memory allocations, we read an entire Pascal-string buffer

52f2a008f1 Update TT_New_Context documentation 
In commit 531d463aed

  [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver.

the `TT_ExecContext` was moved from being on the driver to being on the size
to make it easier to use FreeType in a multi-threaded environment.  However,
the documentation for `TT_New_Context` was not updated and still reflects
the old behavior and parameter list.

This change updates `TT_New_Context` documentation to reflect the current
parameters and usage.
